Fake is a good word. "unjustified and sloppy" is fake to me. We have different definitions of fake and shouldn't get hung up on definitions. My last word on it is I should be antagonistic against people who are deciding what goes in my son's school lunch based off of "unjustified and sloppy" studies.
First principles + received wisdom are counter balancing, not contradicting. Everything in life is a balance.
Definitions matter when it comes discussion, as what you say influences how people feel on a topic. Broad, non-specific definitions leave a lot of space for bias rather than clarity.
If you describe it as 'fake', I consider that to give the impression of 'the answer is NOT' this, and could lead to anti-policy.
If the description is 'unjustified and sloppy', that can lead to additional research to properly invalidate or potentially find something useful, so we don't throw the baby out with the bathwater.
